[PATCH 11/13] staging: rtl8712: Switch from strlcpy to strscpy

From: Kumar Kartikeya Dwivedi <memxor@gmail.com>
Date: 2021-01-31 19:48:41
Also in: linux-tegra, lkml
Subsystem: staging subsystem, the rest · Maintainers: Greg Kroah-Hartman, Linus Torvalds

strlcpy is marked as deprecated in Documentation/process/deprecated.rst,
and there is no functional difference when the caller expects truncation
(when not checking the return value). strscpy is relatively better as it
also avoids scanning the whole source string.

This silences the related checkpatch warnings from:
5dbdb2d87c29 ("checkpatch: prefer strscpy to strlcpy")
